I talked to James CHen of Axis last year trying to get him to start making the Maglite in a bolt pattern for the Celica (5X100) and he said there wasn;t enough room to make it work. it'd be worse with the 5x114.5 we have.
As for tires, we all have our own opinions, but I don't think a beginning autoxer should use race tires AT ALL! Learn how to drive using steet tires of some sort, then once you've learned how to make the msot of them, go to a race compound. Those tires are too expensive to to start on, plus you won't get the same level of skill using the available grip if you haven't tried the lower traction route first.
If I were you, AGR, I'd autox on the RE040s until you kill them, THEN worry about getting better tires. AS for what class to run in, you are currently ILLEGAL for stock! The cone filter and maybe the turbo timer too are NOT allowed in stock!
I'm running in STX because I don't want to spend the money for race tires and new wheels, and I was in STS before, so all my friends are still in STS, AND, I already have a good basis for how to make an ST type car fast.
If you Do decide to get new tires, and opt to NOT go in stock, I'd recommend 15" rims with 205/50-15 Falken Azenis or 16" rims with 215/45-16 Azenis. They are BY FAR the best bang for the buck, and the only tires with better dry traction are BFG KDs which cost about twice as much.
As I've said in other threads, I'm getting a set of 225/45-17 Azenis put on my MSP tomorrow, and I'll let you know how they fit. I've got an autox this coming weekend, too so I can get some solid feedback on how well they do when worked hard too (at least as far as rubbing goes...) I can tell you now that the grip they give is GREAT, but that it will take either 2 or 3 autoxs OR a couple hundred miles of hard street driving to get them up to their full potential. They need to be broken in to grip their best.
Keep them COOL on the autox: they DO NOT LIKE HEAT. AT ALL. I usually spray my front tires with water after each run to cool them off. I've seen the grip go away and the tires get greasy if they are over about 130F. Yes, I use a pyrometer. Like my sig says, I'm an autox fiend
